  • 슬개 대퇴 불안정성의 진단은 정확한 해부학적 지식을 바탕으로 역동적인(dynamic)기전을 이해하여야 한다. 슬개골의 저명한 탈구는 쉽게 진단되지만, 경미한 외상으로 슬개골이 탈구되어 정복된 후에는 올바른 진찰(dynamic study)없이 방사선 검사(static study)만으로는 진단을 놓치는 경우가 많다. 그러므로 정확한 진단을 위해서는 병력, 이학적 검사, 방사선 검사, 전산화 단층 촬영, 자기 공명 영상 그리고 관절경 검사까지 다양하게 필요할 수 있다.

  • A 3-year-old castrated male Spitz dog (8.4 kg) was referred for hindlimb lameness. The dog had undergone corrective surgery for bilateral medial patellar luxation 6 weeks prior to presentation. Intermittent lameness of both hind limbs was evident on general inspection. Physical examination revealed moderate pain and crepitus upon flexion and extension of the stifle joints. Radiography revealed features consistent with distal deviation of the cartilage flaps and effusion in both stifle joints. Detachment and deviation of both osteochondral blocks were suspected based on the physical and radiographic findings. Arthroscopy confirmed failed osteochondral blocks (right $1.5cm{\times}0.9cm{\times}0.2cm$, left $1.3cm{\times}0.9cm{\times}0.1cm$), which were removed. After removal of the osteochondral blocks, the stepped trochlear grooves were located and debrided using an arthroscopic burr, to prevent patellar tracking disorder. The dog resumed normal ambulation without medial patellar luxation 2 weeks postoperatively, and there were no complications. Arthroscopy is an effective surgical modality for the diagnosis and treatment of canine joint disorders. It offers a magnified view of the joint, which allows accurate evaluation of intra-articular structures. In addition, arthroscopic surgery can reduce the postoperative complications associated with surgical wound.

  • Purpose: To investigate the outcome of arthroscopic treatment for the complications of knee arthroplasty and to evaluate the effectiveness of arthroscopy. Materials and Methods: We analyzed 25 patients who underwent arthroscopy to treat complications of knee arthroplasty between May 1992 and June 2008. Nineteen cases out of 25 had total knee arthroplasty (TKA) and the remaining 6 cases had unicompartmental knee arthroplasty (UKA). Before arthroscopy, physical examinations and radiographic evaluations were carried out to find out the causes of complications. Joint fluid aspiration and hematologic evaluation were added when infection was suspected. Results: Among the diagnosis at the time of arthroscopy, there were 11 cases of infection, 6 cases of stiffness due to adhesion and fibrosis, and 2 cases of soft tissue impingement in the cases of TKA. Among the cases of UKA, one for each case of meniscal tear, subluxation of mobile insert, hemarthrosis, cement loose body, soft tissue impingement, and stiff knee was found. Nine out of 11 patients who had infection were treated successfully with arthroscopy but the remaining 2 cases underwent revision arthroplasty. Seven patients with arthrofibrosis had improved range of motion from $65^{\circ}$ preoperatively to $105^{\circ}$ postoperatively. The others also showed successful results after arthroscopy. Conclusion: Arthroscopy to treat complications after knee arthroplasty was a safe and effective method when appropriate selection of patients was made.

  • Purpose: We reported the results of arthroscopically assisted lateral release and medial imbrication for the recurrent patella dislocation. Materials and Methods: Twenty patients (20 knees) underwent arthroscopically assisted surgery for the recurrent patella dislocation. There were 4 males and 16 female. The average age was 20.2 years. All patients had definite trauma history and average follow-up period was 19 months. The surgical results were evaluated according to the Lysholm knee score and the Kujala score. The congruence angle and lateral patellofemoral angle were measured on plain radiograph and the tibial tubercle-trochlear groove distance was calculated on computerized tomography. Results: The median value of preoperative congruence angle was $16.5^{\circ}$ (range, $0.0{\sim}+34^{\circ}$) and the average final follow-up was $-6.4^{\circ}$ (range, $-19{\sim}10^{\circ}$) with statistically significant improvement (p=0.025). The median value of preoperative Lysholm knee score was 70 (range, 63~81) and the final follow-up score had changed to 88 (range, 80~95) with statistically significant improvement (p=0.0341). The median value of preoperative Kujala score was 72 (range, 65~80) and the average final follow-up score showed 87 (range, 80~92) with statistically significant improvement (p=0.024). Recurrent dislocations after surgery occurred in 2 cases, one case which showed positive "thumb to forearm test" had been treated with medial patellofemoral ligament reconstruction. Conclusion: Arthroscopically assisted lateral release and medial imbrication for recurrent patella dislocation without bony malaligmenent showed the effective treatment, but would be inappropriate for the patients with the generalized joint laxity.

  • A 10-year-old intact female Chihuahua weighing 2 kg was presented for complaint of forelimb lameness with non-weight bearing posture. Greater tubercle was palpated medial to its normal location on palpation and crepitation was intermittent with manipulation. On radiographic examination, left medial scapulohumeral joint luxation was found. Bilateral medial patellar luxations also were found and evaluated as grade III. Surgically, the medial scapulohumeral joint luxation was reduced with transposition of the tendon of the biceps brachii muscle. The patient's gait became normal and non-weight bearing posture was resolved at 6 weeks postoperatively.

  • A 5-year-old castrated male Chihuahua weighing 1.54 kg was examined because of a several month history of progressive right hind limb lameness. Physical examination of the stifle joints revealed pain and a grade IV medial patellar luxation on the right stifle joint. The right and left stifle joints were associated with a lameness of grade 2 and grade 0, respectively. Radiography revealed osteophytes or subchondral cystic lesions on the right and left stifle joints. Osteoarthrosis (OA) scores for the right and left stifle joints were 20 and 12 respectively. Combination of surgery and implantation of autologous adipose tissue derived mesenchymal stem cells (aAT-MSCs) was determined with informed consent. $1{\times}10^6$ aAT-MSCs suspended in PBS and 0.6 mL of hyaluronic acid were injected in the right stifle joint postoperatively. Osteoarthrosis scores and the lameness grade for the right and left stifle joints were 19 and 13, and 0 and 0 19 months after treatment, respectively, and 14 and 15, and 0 and 0 five years after treatment, respectively. This case report shows radiographical evidence of a decrease in osteophytes and subchondral cystic lesions on the stifle joint with OA after aAT-MSCs injection.

  • Purpose: To evaluate the results of percutaneous lateral release and arthroscopic medial plication for patients with recurrent patella dislocation. Materials and Methods: This study includes the thirty-one cases of patients who have had a surgical operation from March 2001 to March 2008. All the patients had recurrent patella dislocation after trauma history. The average age was 24.2 years old and the average follow up was 47.4 months (minimum 24 months). Results: The preoperative congruence angle, lateral patellofemoral angle, Lysholm score was $24.8^{\circ}$, $-6.2^{\circ}$, 75 points on average respectively. However, the postoperative congruence angle, lateral patellofemoral angle, Lysholm score was improved to normal range: $-2.8^{\circ}$, $10.2^{\circ}$, 95 points on average. Five cases showed the recurrent dislocation after operation. Among them, three cases showed femoral trochlear dysplasia. Conclusion: Percutaneous lateral release and arthroscopic medial plication showed satisfactory results for recurrent patella dislocation with low complication rate. However, in cases with femoral trochlear dysplasia, another surgical treatment may be considered.

  • Purpose: To evaluate the clinical and radiological outcomes, and the complications of unicompartmental knee arthroplasty (UKA) using a fixed bearing prosthesis after 5-year follow-up. Materials and Methods: Twenty-six knees (25 patients) that underwent fixed bearing UKA between May 2003 and August 2011 were included. The subjects were 3 males (3 knees) and 22 females (23 knees), and the average age was 63.5 years. The preoperative diagnosis was osteoarthritis (23 knees) and osteonecrosis (3 knees). The mean follow-up duration was 67 months (from 60 to 149 months). The clinical evaluation included pre- and postoperative American knee society knee and function score, and range of motion. The radiology evaluation included standing antero-posterior, lateral view, and fluoroscopic film to analyze the postoperative alignment and osteolysis. Results: The mean American Knee Society knee score and function score were improved from 42.0 and 57.5 to 87.9 and 85.0, respectively (p<0.001). The mean preoperative and postoperative range of motion was $132.9^{\circ}$ and $132.5^{\circ}$, respectively. The mean femorotibial angle were varus $0.5^{\circ}$ preoperatively and valgus $2.2^{\circ}$ postoperatively. A radiolucent line was observed in 2 knees; one knee had a stable implant, while in the other knee, patellofemoral arthritis was identified during UKA. Diffuse pain of the knee joint with tenderness of the medial joint line was identified at the follow-up, so conversion to total knee arthroplasty was recommended. No other complications, such as osteolysis, infections, postoperative stiffness, and dislocation, were encountered. Conclusion: The midterm results of fixed bearing UKA were clinically and radiologically satisfactory.

  • Purpose: To evaluate the long-term clinical results and survivorship of unicompartmental knee arthroplasty (UKA) in elderly patients older than 70 years by analyzing cases that have been implanted for >10 years ago. Materials and Methods: The long-term follow-up results were evaluated in 39 patients (46 cases) who underwent medial UKA from March 2002 to February 2004. The mean age of the patients at the time of surgery was 74.0 years, and the preoperative diagnosis was degenerative arthritis of the knee in all cases. Results: Of the 46 cases, reoperation occurred due to the complications in four cases. In 22 cases without 14 cases of death and six cases of follow-up loss, follow-up more than 10 years was possible. The mean Knee Society knee and function scores improved significantly from 53.0 and 52.5 points pre-operatively to 89.4 and 80.9 points at the last follow-up, respectively (p<0.001). The mean range of motion of the knee recovered to 132.5°, and the mean tibiofemoral angle changed to 5.9° of valgus at the last follow-up. Complications following the UKA occurred in four cases; the most prevalent complication was mobile bearing dislocation (n=2). One case of failure occurred due to aseptic loosening and degenerative arthritis of the lateral compartment, respectively. The cumulative survival rate of the implants was 95.0% at 10 years and 85.7% at 15 years. Of the 40 cases, excluding six cases of follow-up loss, 36 cases (90.0%) could be used without reoperation until death or at the last follow-up after surgery. Conclusion: These results showed the outstanding functions of the knee and satisfactory long-term survivorship after UKA. Therefore, UKA could be a useful method for the treatment of osteoarthritis of the knee in elderly patients older than 70 years of age.

  • Purpose: The authors introduce a new technique of arthroscopic reduction of subluxed medial meniscus using suture anchor for the restoration of hoop stress. Operative Technique: Anterolateral, anteromedial, and medial midpatellar arthroscopic portal are used. Arthroscope was inserted through anterolateral portal. Through the scope, we confirmed subluxation of medial meniscus. Transection of menisci including radial and root tear were excluded. We released the anterior horn of medial meniscus through anteromedial and burred the future insertion site of suture anchor. After inserting suture anchor through medial midpatellar portal, we used 90 degree suture hook and no.2 Nylon to retrieve the suture of inserted anchor. We tied the suture by sliding knot-tying method. Weight bearing was limited for 6 weeks postoperatively. Conclusion: Arthroscopic retightening of medial meniscus is less invasive, conserving and progressed method for subluxed meniscus.
